Dicentra plant named &#39;Amore Rose&#39;

ABSTRACT

A new and distinct form of  Dicentra  plant characterized by its soft, feathery blue green foliage, a compact habit, medium dark rose flowers on short flower stalks, repeat blooming, and good vigor.

BOTANICAL DENOMINATION

Dicentra hybrid

VARIETY DESIGNATION

‘Amore Rose’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofDicentra, of the family Fumariaceae, known by the cultivar name, ‘AmoreRose’. This plant originated from planned cross between. The seed parentis Dicentra ‘Burning Hearts’, U.S. Plant Pat. No. 20,797, and the pollenparent was a proprietary unreleased Dicentra hybrid seedling (Dicentraperegrina×(D. formosa subsp. oregana×D. eximia)). This seedlingselection stood out with its unique characteristics.

This new cultivar is uniquely characterized by:

1. soft, feathery blue green foliage,

2. a compact habit,

3. medium large deep rose flowers on short flower stalks,

4. repeat blooming over a long season, and

5. good vigor.

Compared to the seed parent, Dicentra ‘Burning Hearts’, U.S. Plant Pat.No. 20,797, the new cultivar a bigger habit, and bigger leaves that areless silver. The new cultivar is a more vigorous plant and longerblooming.

Compared to the pollen parent the new cultivar has better foliage color,habit and a distinctive flower color.

The new variety has been reproduced only by asexual propagation. Each ofthe progeny exhibits identical characteristics to the original plant.Asexual propagation by micropropagation as done in Canby, Oreg., showsthat the foregoing characteristics and distinctions come true to formand are established and transmitted through succeeding propagations. Thepresent invention has not been evaluated under all possibleenvironmental conditions. The phenotype may vary with variations inenvironment without a change in the genotype of the plant.
